Patented Dec. 6, 1910. Serial No. 368,473.

To all whom it may concern:

Be it known that we, JAMES RAMSEY Srnnn and GEORGE H. HARVEY, citizens of the United States, residing at Pittsburg and Glenfield, respectively, in the county of Al- I such amanner thatyany cylinder or pair of cylinders in either riw may be detached ,from the drawing mechanism and lowered to a horizontal position. It is to be understood, however, that, although we show our apparatus particularly designed as specified. we do not restrict ourselves to the same, as our invention hasinarked when arranged to act in conjunction with an apparatus for drawing a single article.

eferrlng to the drawings which form a part of this specification, Figure l is a side elevation of our invention, broken away in parts and showing at the right the drawing apparatus with a cylinder at the initial stage of the'drawing operation, and at the left the drawing apparatus with a cylinder atthe conclusion of the drawing operation,

advantages even of glass-drawing furnaces and lay a track parallel with and between said rows of furnaces We preferably arrange our furnaces 1n pairs, the pairs in one row being opposite those in the other row. On said track we I place a carriage having travel thereon. at,

right angles to said track and carrying a device capable of receiving and lowering: pair of cylinders from any pair of furnaces in either row. g I

, )n Fig. 2 we have shown the two pairs of furnaces A and C in one row and the two pairs of furnaces B and D in the other row, the furnaces B and D being directly opposite the furnaces A and C.

E represents the truck having travel on naces, and G represents the carriage movable transversely of the truck on the rails e.

The drawing apparatus is substantially the same as shown in our United States Patent, No. 813,248, dated February 20, 1906, except that itis modified so as to coiiperate with a pair of furnaces instead of with one.

structed as follows: Slidable vertically. on the standard or column 1 is the carriage 2, which may be controlled in its movements by the screw 3, as in our said patent. The car- I Each drawing apparatus is preferably coneach having the front bracket 5, in the fork of which sits the hollow stem 6 of the drawing tool or bait 7, the stem having the collar 5 S resting on the top of t bracket to cause i the bait to travel up with the carriage but l permitting the bait to bereadily lifted oil the cylinder-lowering apparatus being in its from the bracket. Each arm also carries the vertical position. F 1g. 2 is a plan showipg the drawing operation completed at the pair of furnaces A and the cylinder-lowering ap'- paratus with a pair of cylinders thereon in its horizontal position; the drawing opera tion about to begin at the pair offurnaces B; the drawing mechanism at the pair of furnaces C in section on the line 2-2 on Fig. 1; and the super-structure removed from the pair of furnaces D. Fig. 3 is a side elevation of the lowering apparatus looking to the right on Fig. 2. Fig. 4 is a plan of the lowering apparatus in its vertical position with its super-structure and operating means omittedl Fig. 5 is a detail. in frontielevation, with parts broken away. Preferably we provide two parallel rows valve cylinder 10, in which slides the hollow I connection 11, whose lower end fits air-tight connection 11 is reciprocated by the lever 12 pivoted on the post 13 and actuated by thr chain l t' within reach of the operator of the drawing apparatus. Air is supplied through the pipe 15to the connection 11, the stem 6 and the interior of the cylinder'as they are drawn, as set forth in our patent hereinriage has the oppositely extending arms 4,'

1n the'upper end of the bait-stem 6. The 95.

,7 i, the rails F parallel with the rows of furtoo I above mentioned. The members of each pair of furnaces are arranged under the respective drawing apparatus, so that the center of each drawing pot 16 will: be directly below the center of the bait 7 whensuspended on the brackets.

' The carriage G has the wheels 17 running on the heads of the rails e, and the wheels 18 engaging the underside of the said heads to prevent the carriage from overturning. Other means may, however, be provided to secure the same result. The carriage G rigidly supports the tower 19, having the end standards 20 and the cross-piece 21, which connects together the tops of the standards. In the lower ends of-the tower is a rock shaft 22 parallel with the rails F and actuated by the motor 23 through the intermediate reducing gears 21.

Rigidly secured to the shaft 22 is the mast 25, which when vertical extends up nearly to the top-piece 21 and has at its upper end the clevis 26. To the clevis is secured one end of the cable 27, which passes up between the two idlers 28 and 29 and then over the two idlers 30 and 31 on the top of the tower 19. From the idler 81. the cable passes beneath the wheel 32 and then up to the extension 33 of the top-piece 21. The Wheel 32 carries the counterweight 34, which counter-balances the mast 25 and its appurtenances.

To the mast 25 is secured a number ofcollars 35, from each of which extend the four arms 36, the outer end of each arm having the fork 37. The forks are arranged with one pair on one side of the mast so as to partially embrace simultaneously a pair of completely drawn cylinders, theother pair of forks being on the opposite side of the mast and arranged to receive a pair of cylinders on the opposite side of the track F from those which the first named pair of arms, may receive. The forks have linings 38 of some non-conductor of heat.

The top collar 35 has the four arms 36, and the forks37, all'the same as the parts 35, 36, and 37 except that the forks 37 are nade small so as to receive and support the stem 6 of the bait.

A collar 35 near the bottom of the mast. :arries the jointed arms 36 having the cylnder-supporting forks 37 the joint permit- ;ing the outer sections of the arms to flex on he base of the carriage G as shown on Fig. 2. The joints are used because the arms are onger than the distance of the forks from .he said base.

Above the collar 35 is the collar 39 having he arms 10, which support the parallel hori- -;ontal bars 41, extending at right angles to .he columns 1. Each bar 41 has at each end a -air of levers 42 having one end adapted to ngage the pin 43 extending out laterally rom opposite sides of the'bait stem (3, the pposite ends of the levers being pivoted to ac end of the links 44:. The remaining ends f the links are secured to the opposite ends f the levers 45 on the rock shaft 46. The nks connected to all four of the levers 4:") re connected to the rock shaft 46, which has horizontal arm 47, which is connected bv shown in Figs. 2 and 3.

e link 48 to the arm 49 on the rock-shaft mounted on the base of the tower. The arm 49 is actuated by the hand-lever 51. which may be locked in any desired position by means of the pin 52 and the holes 53 in the stop-plate 54.

The operation of our invention is as follows: Assuming that molten glass is contained in a pair of pots 16, the correspond mg carriage 2 supporting a pair of drawing tools or baits T is lowered until the lower ends thereof are immersed in the glass. where they remain until the glass adheres to them. Then the carriage is raised and the two cylinders 55 drawn in the well known manner. After the cylinders have been drawn to the desired length, they are severed from the glass remaining in the pots, as shown in Fig. 1. Fig. 2 showing at the apparatus.& the cut-off lower ends 56 of the cylinders in the pots.

The truck E and the carriage (i are moved so that the left-hand pairs of forks on the mast are opposite the cylinders 55, the carriage G with the mast vertical is pushed to the left until the outer ends of the levers 4-2 pass. beneath the pins 43 on the bait stems ('3, the lever 51. is actuated so as to cause the levers 42 to lift the baits and cylinders off from the forked brackets The chains 1st 'are now or have been actuated to raise the connector pipes 11 away from the bait stems 6. The lever 51 is then locked by the pin 52 placed in one of the holes 03. The motor 23 is then started in the proper direction to swing the mast with its load toward the right. until it lies in a horizontal position, as

During this operation the cable is drawn against. the'idler 28, and the lower arm 36 flexes as shown in Fig. 3. The cylinders are now horizontal and may be cracked off from the bait and elsewhere at the dotted lines, Fig. 3, the cylinder-sup porting arms Btlbeing arranged in pairs along the mast so that when the cylinders are cracked off between the members of the several pairs the ends of the sections will be supported on the arms of adjacent pairs. The collars on the mast being made in sections bolted together, may be adjusted along the mast so as to support the cylinders at any desired place.

After the removal of the cylinders and baits from the lowering machine, the motor is reversed and the machine raised to the vertical position. The lever 5l'is retifrned to its starting position so as to lower the outer ends of the lifting levers 42. The lowering mechanism may be shifted so as to lower the two cylinders which will by this time be fully drawn at the apparatus B. The operation described is repeated. The lowering mechanism is arranged so its to cooperate with any of the drawing appa-' ratuses in either row.
